Acute dorsal myelopathy resulting from intramedullary cysticercus: a case report.

BACKGROUND

Neurocysticercosis is the most common parasitic infection of the central nervous system, brain being the most frequent site. Intramedullary location of cysticercus is a rarely described entity in literature. Widespread dissemination of cysticercus is also considered a rare occurrence, and only a handful of cases are documented, almost exclusively from tropical nations. Here we present a case of disseminated cysticercosis with rare initial presentation as acute dorsal myelopathy resulting from intramedullary cysticercus.

CASE PRESENTATION

A 62-year-old male patient from India (Asian) presented with features of dorsal myelopathy as manifested by acute-onset symmetric paraparesis, sensory loss below umbilicus, and double sphincter dysfunction. General physical examination revealed pea-sized nodules in skin and tongue. On spinal cord imaging, it was found that he had intramedullary cysticercus with diffuse perilesional edema. Brain and muscle imaging showed extensive cysticercosis suggestive of dissemination. Histological examination from skin nodule and antibody assay confirmed the diagnosis of cysticercosis. Following steroid administration, our patient showed improvement with observable increase in power of the lower limbs. He was subsequently discharged with antiepileptics, symptomatic therapy, and regular physiotherapy. Antihelminthic agents were initially avoided in view of extensive cysticercosis in brain including crucial areas such as brainstem.

CONCLUSION

Rare manifestation of a rare but treatable disorder makes it an important reportable observation in the context of tropical medicine.
